If the EGR valve is closed (it should be, as its unplugged) nothing should flow down that pipe.
And as you've blanked the inlet elbow, that won't be sucking/blowing anything through the pipe either.
So should all be fine unless your EGR valve is stuck open a bit, in that case you'll end up with soot coming out lol.
